Depends on the proxies. I believe that if apache is the last proxy, it will remove any previous values and write the IP address of the last proxy in X-Forwarded-For. There is no general way to tell the original client's IP address. It all depends on the proxies involved. > In order to leave intact the application on the backup server, could we use > a setenv mechanism on the backend server, in order to rewrite the > remote_addr variable with the x_forwarded_for variable ? No. This would require a custom apache module. (It probably wouldn't be too complicated, but you would need to be very careful about security issues.)
